Skid of embedded medium-low speed maglev train maintenance platform

The invention discloses a skid of an embedded medium-low speed maglev train maintenance platform. The skid comprises a hollow shell crossing two sides of a rail and power supply rails arranged on theshell in parallel, wherein the shell is connected through a plurality of cross beams, a plurality of rail wheels and a plurality of radial positioning structures thereof are arranged in each shell, the radial positioning structure comprises a shaft and a key, the shaft horizontally penetrates through the rail wheel and stretches across two sides of the shell, keys are arranged in a key groove of the shaft and a key groove of the rail wheel, axial positioning structures used for ensuring that the rail wheels and the shafts are relatively static in the axial direction are arranged on the two sides of the rail wheels, and the axial positioning structure comprises a spacer sleeve, a bearing and a check ring. The skid is advantaged in that a technical problem of high driving energy consumptionin the maintenance process of a maglev train in the prior art is solved, and the skid has advantages of compactness, reliability, convenience in maintenance, simple structure and the like.
